The goal of this study is to reduce the incidence and severity of occupational musculoskeletal injuries in nursing through the redesign of stressful patient handling tasks. This study addresses three objectives: 1) conduct a quantitative, biomechanically based, ergonomic evaluation of the eleven "at risk" tasks in nursing practice; 2) redesign the techniques or equipment needed to perform these tasks safely or with reduced risk of musculoskeletal injury; and 3) conduct laboratory- based assessment of the biomechanical benefit of the proposed intervention strategies.
